Yes but you'd need a component (virtual, software, hardware, machinery, people... whatever) to manage in a queue (meaning lead time + process time) things than can be instantly dealt with and only occasionally have to be properly worked - it's like the Branch Target Prediction in CPU. You execute one of the two branches without checking and go on but before finalizing the operation you'll have the proper check executed. If the prediction was right you avoided a useless wait and bubble in the pipeline, if the prediction is wrong you pay double price. With a prediction rate high enough the overall performances are improved.
Also look at when there are problems: the checking component (office, server, whatever) is non-functional or under performance (50% missing people in the office, server down, peak of activity). Avoiding the queue means that EVERY legit refund will still be immediate and nobody would ever knwo there is some problem. Only non legit refunds end up in the now non-functional queue, but they are a minority, which means that Amazon won't have thousands of people running after them with tens of support requests and bad publicity for not having received a refund in the expected time.
At leat that is how I interpret the procedure, it is an affirmed logistical solution and many other big companies employ it.
Today my English sucks particularly so I'll try with an example, hoping to express myself a bit better than a baboon.
Let's put the two cases at work, case 1: each package must be confirmed then refunded, case 2: as it is now, refund and then eventually take it back. We have Alice, with a legit refund, and Bob, which has a package that cannot be refunded. Two scenarios: 1 everything is 100% operational, 2 there is some problem in the checking office such that they have a month of job late.
Scenario 1, Case 1 - Everything operational, every package checked and then refunded if eligible.
Alice sends her package back. In a couple of days she receives her refund. She's satisfied.
Bob sends his package back. In a couple of days he receive notice that he cannot be erfunded. He may have other complaints but he's served.
Scenario 1, Case 2 - Everything operational, instant refund and then check.
Alice sends her package back and gets her refund instantly. She's overjoyed and needs no more work.
Bob sends his package back. He receives his refund instantly, then after a couple of days Amazon takes it back and notifies him. He may have other complaints but he's served.
Scenario 2, Case 1 - Office not operational, every package checked and then refunded if eligible.
Alice sends her package back. After a week she has'nt received the refund, she grows anxious and nervous. She opens a ticket on the support. After two weeks she's distressed, the interactions with the support are intensifying. She's becoming distrusting and angry, possible bad publicity. After three weeks the situation is escalating, she's putting bad reviews and angrily threatening legal actions, support calls are mor than daily. After a month she's served but very dissatisfied and will probably look for competitors the next times.
Bob sends his package, does not receive anything, does the same thins as Alice and then his refund is negated. He's angry like a viper, starts cussing Amazon everywhere, won't buy again.
Scenario 2, Case 2 - Office not operational, instant refund and then check
Alice send her package, receives refund. She's happy and satisfied. After a month Amazon knows her refund was legit. No work to be done.
Bob sends his package, receives his refund. After a month Amazon knows he wasn't eligible and taks the refund back. The customer may have other complaints but he's served.
As you see the Case 2, which is the as-is situation, is less vulnerable to bottlenecks and that improves the time to completion of the operations with respect to the customer.
Where's the nearest Amazon depot? Is it impossible that they'd actually received the package by then? Maybe they just ask UPS to open any returns and store them up for one big shipment? Maybe UPS is trialling a teleporter for NASA? Or perhaps Amazon has a number of x-ray demons ready to fly to UPS offices at a moment's notice at all times. I wouldn't put anything past them.
Or, the UPS Store has a time machine. Or, aliens in fast spaceships deliver their packages. Or, I was knocked unconscious and UPS changed all my clocks. Or, a bubble of natural gas exploded and refracted off of a weather balloon. Or, ...
There are only 10 types of people in the world, those who understand binary and those who don't.
The chances of me not finding this on YouTube are a million to one they said... Yet I could not find it!
I almost had to resort to my #2 of the week!
Luckily I found a recording on Vimeo that sounds close enough to the original record
Awesome song, awesome album. Listened to it a couple of times and then a couple of times more because this song (and the entire album) is so awesome.
Aliens invading my home and threatening to disintegrate me with their heat ray if I didn't make this my SOTW had nothing to do with it
